I'm writing a script to count the number of times three users have logged into the servers. Where do I start (in BASH).

Welcome to LQ.

The first line of the script where it says:

Code:

#/bin/bash

Next, please read the My Bash Blog link from my signature which describes some techniques for writing bash scripts, as well as offers other bash references.

who will tell you who is logged on. See: man who
You don't say if you are using systemd. If so journalctl will you some info on that like sudo. Then there is /var/log/auth.log

To get the last logins of kbbeard51

Code:

last kbbeard51

Or you can run last to see all.
